Ohh, so the distance between field lines coming out of a charge does indicate the strength of the field around the charge also!

Anything obviously missing would mean that for a vector diagram, I can tell what all the charges roughly are..?

In drawing a line diagram for more than one charge, can I say I first look at charges, then draw how they interact with each other--and if there's another charge, how they interact with each in an area furthest away from that charge being currently ignored--then move onto the interactions between another pair if there's more charges, and finally draw field lines for each charge depending on the strength of each charge?
...drawing field diagrams seems almost odd to me :/. The teacher said something about getting familiar and developing an intuition for them, so maybe there isn't an easy to follow process for it?
